SPECIFICATION forming part of Letters Patent No. 385,329, dated June 26,1888.

Application filed February 18, 1888. Serial No. 264,461.

To all 10.720722 it may conoci/'71,:

Be it known that I, CHARLEs I-I. STRATTON, of Salem, in the county ofColumbiana and State of Ohio, have invented certain new and usefulImprovements in Vehicles; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to an improvement in vehicles, and moreparticularly to improve the construction ofjump-seats and adjustableshifting dashes of carriages, buggies, and other similar conveyances.

One ofthe obj ccts to be attained by my present invention is to soconstruct and connect the supporti ng'irons of front and rear seats of avehicle that the rear seat may be advanced so as to locate it near thecenter of length of the body and the front seat be folded beneath therear seat to afford room for the feet of 0ccupants of this single seat,and also lock this rear seat in such forward adjustment automatically. Y

A further design of this invention is to afford a meanswhereb'y therelative position of the connected front and rear seats of the vehiclemay be changed so as to permit the rear seat to be located in its normalposition at the rear of the vehiclebody and the front seat forwardlylowered to a prostrate position at the front of the body near the dash,the lowered front scat and upright rear seat being automatically lockedin the positions just mentioned by the act of moving them into place.

A further object is to so arrange and combine the jointed supportinglegsof the front and rear seats of a vehicle that the rear seat may beadjusted to its normal position at the rear end of the vehicle-body andthe forward seat be elevated for use in spaced position with regard tothe rear seat, the front seat being automatically locked by rear seatmovement in assuming its relative position.

Afurther object is to provide the body of a vehicle that is designed forthe use of jump-` seats with tie-irons vthat are so combined with thepivotcd limbs of a rear seat that these seat-supports and the rear seatitself are made to tie together the sides of the vehicle-body, toprevent its lateral disruption by the spreading (No model.)

action of the weight of the occupants of the rear seat.

dashboard being locked together to prevent` accidental displacement fromthis relative adjustment of parts, and, if desired, permitting theforward movement of the front seat to recline it near the dash withoutaltering the forward adjustment ofthe latter; andin case the forwardseat is in reclining position, either forward, as just alluded to, orrearward,to lie under the rear seat, which latter is advanced to wardthe center of length of the vehicle-body, to be used as a single seat,the dash will beinwardly drawn by the act of moving the rear seatforward, so as .to contract the space between the dash and single seat,thus affording a neat appearance to the vehicle when this adjustment ofparts is effected.

A further object is to provide hinged orV jointed armrests for the frontseat of a pair of connected jump-seats, to permit these arms to folddown on the cushion of this seat when it is lowered or shifted to lieunder the rear seat or other lowered positions.

A further object is to furnish a connected set of jump-seat irons for atwoseated vehiconsists in certain features of construction andcombinations of parts, which will be hereinafter described, and pointedout in the claims.

Referring to the drawings accompanying this specification, Figurel is aside elevation, in section, of the body of a vehicle and two sets ofconnected seat-irons with seats mountedv on them, being elevated foruse, and the dash shown projected forwardly. Fig. 2.' is a sideelevation, in section, of a vehicle-body with IOO two sets ofjump-seatirons and attached seats in place, the rear seat bein g advanced for useas a single seat, the front seat being lowered and projected beneath therear seat, and the dashboard inwardly drawn to contract space between itand the single seat. Fig.v 3 represents the vehicle-body in section,with two jumpseats in the same,the rear seat being advanced and lockedin place near the center of length of the vehicle-loody,and the forwardseat lowered toward the dash,thus automatically locking the parts, thedash being rearwardly moved to reduce the space between it and theadvanced rear seat. Fig. 4 is a side elevation, in section, of thevehicle-body, and shows the forward seat in a forwardly-depressedposition near the dash and the rear seat adjusted nearthe rear end ofthe vehicle-body. Fig. 5 is aside elevation, in section, cfavehicle-body with a modified form ofjump-seatirons, and a slidingdashboard,shown connected to the legs of the rear jump-seat, so as toautomatically move when this seat is changed in position.

Fig. 6 is a rear elevation of the vehicle-body shown in Fig. l, with theseats upright and the rear end of the body removed to show the relativeposition of the seat-irons. Fig. 7 is a rear elevation of the body of avehicle, with the rear end removed, the jump-seat irons shown in Fig. 5being represented in this view. Fig. Sis a plan view of the vehicle-bodyand seatirons shown in Fig. l, the ends of the seat-boards being brokenaway to expose the irons.y Fig. 9 is a front end elevation of thevehicle-body with the dash in retracted position, as shown in sideelevation in Fig. 2. Fig. 10 is a cross-section ofthe front sill of theve` hicle-body, also the mechanism by which the dash-board is shiftedVoutward or retracted toward the seat, the latter being in elevation.Fig. 1l shows a side elevation of the front of a-vehicle, having arectangular box-body ori piano-body with the movable foot-board appliedthereto.. Fig. '12 represents alongitudinal elevation,in section,ot' avehicle-body with two connected .jump-seats, both in elevated positionfor use, the front seat having folding side-arm rests that are jointedto fold on the cushion, asliding dash being also shown which isconnected to the legs of the rear seat. Fig. 13` lis a frontelevation ofthe front seat, showing the folding side arms in elevated and foldedposition, the latter in dotted lines.

The rocker-plates A of the seat-irons constitute the base-pieces uponwhich these irons are pivoted to be adjusted and given requiredpositions with regard to each other. These plates A are made from flatmetallic bars, preferably of iron` or-soft steel, and are secured byscrews or other means to t-hc inner edge of the sills or bed-frame B ofthe vehicle-body A2, thus stiffening the side sills of this frame, asthe sustained load strain comes edgewise upon the rocker-plates. Therear ends ofthe rockerplates A` may be lturned outwardly to bear uponthe top surface of the bed-frame B at the points B.

'At A the rocker-plates A are bent upwardly in an inverted-U shape toafford integral vertical brackets, upon which t-he rear limbs, C,

of the rear seatare pivotally supported. The

pieces Dl maybe paneled or otherwise finished upon their exterior surfaceto give the exposed ends of the seat an ornamental appearance.

v Integral with the lower edge of the rear-seat plate, E, the dependingstandards E are projected downwardly about at right angles to these'plates to form legs or supports for the seat D, (see Fig. 6,) and itwill be scenin this transverse view of the vehicle-body and rear seatthat the rear limbs, C, are bent laterally in easy curves tothrow theirupper edges outward a proper distance to engage the seatplates E attheir rear ends, the depending standards E resting with their lower freeends upon the bent ends B of the rocker plates A.

At the forward ends of the rear-seat plates,

E, the front limbs, F, of the rear seat, D, are

pivoted upon Athe side surfaces of these plates, and the lowerends ofthese front limbs, F, are pivoted to the upwardly-turned integralprojections a. of the rocker-plates A, said projections a being firstbent outward to lie closely upon the top surface of the sills B, and besecured to the same by screws or other means. The outward and upwardprojection of the pieces a, just described, are so made to cause theouter faces of the vertical portions of the same to properly line withthe frontlimbs, F, of the rear seat and permit a free action ot' theseat on its pivoted limbs.

It will be noticed that by the method of construction ofthe rear-seatlimbs just described and their connection with the rocker-plate A thefront limbs will work near to the adjacent sides G-of the body of thevehicle, while the rear limbs are connected and bent so as to allow aspace to intervene between a front and rear limb at each side of theseat. In Figs. l and.2 another form of rear seat support is shown, whichmay be employed when the standards E in said figures are not used.

Upon the sides G of the vehicle-body, near the top edges ofthe same, theseat-supporting strips or upper body-rails, G', are attached. These` aredesigned to give a support to the seat D by contact of its ends withthen-.top edges, and as the strips G are extended parallel to each otherand a proper distance from the bottom of the body itis' evident that thelimbs of the rear seat, D, may be vibrated upon their points of pivotalsupport, and this seat be caused to rock forward and rest in such aposition of forward adjustment as will be necessary to suit its uses asa single seat when the front seat is folded or lowered, as will behereinafter explained. j

Preferably near the top edge of the seat-supporting strips G theelongated tie-bars H are affixed by their ends b to the sides of thevehicle-body. These tie-bars are made of metal of suitable thickness togive necessarystrength. They are bent at right angles at each end of thebar in the same plane to produce short limbs, by which the bars areattached to the sides of the'vehicle-body, as stated. The tiebars H,from their position on the inner surface of the sides of thevehicle-body,are made to afford slots that extend between the bent endsb of each tie-bar, the width of these slots being represented by thespace intervening between the bars H and the opposite sides ofthevehicle-body.

The front limbs, F, ofthe rear seat, D, are located to work freelybetween the tie-bars H and the sides of thebody and have a bearing-4contact with the adjacent bars, so that aseat board or frame, D, mountednponand secu red to the end blocks or pieces, D',of the rear-seat ironswill, by its positive connectionwith the forward limbs, F, of the rearseat, coact with y the same to tie the sides of the vehicle-body toresist a bursting strain that the weight of the occupant of the seat mayoccasion.

The tying together of the sides of the vehiclebody in the mannerjuststatedis particularly necessary and valuable when the standards Eare dispensed with, which may be desired in' some forms of vehicleconstruction, asin this case the entire weight .of parties who occupythe rear seat will be imposed upon the strips G', and without the tyingtogether of the sides, as provided fon/these light sides might beoutwardly forced and injured by heavy weight placed upon the seat D. Y a

In case it is preferred to use the standards E to support the rear seat,D, the strips or top body-rail, G', may be dispensed with, as shown inFigs. 3 and 6, so as to depend solely on the standards Ey for arear-seat support independent of the body of the vehicle.` In thislatter-named form of construction the ends of the seat D have no contactorconnection whatever with the inner surface of the sides of thevehicle-body. a The forward seat; l, is secured upon the end blocks, l',(see Fig. 8,) which latter are made of any suitable material, preferablywood,and are given any preferred shape or finish on the outer surfacetoi suit the styleof the vehicle vand harmonize with the style andformof the rear scat and blocks or pieces D'. The end blocks, l', areaffixed by screws or otherwise to the seat-plates c, which latter arepivotally secured at each end to the front and rear legs, J K. rlhefront legs, J, and rear legs, K, of the front seat, Lare also pivoted attheir lower extremities to the inner surface of the rockerplates A, thefront legs being curved edgewise to project their cnrvededgesrearwardly,while the upper ends of the rear legs, K, are curved in anopposite direction, or with the projecting portion toward the front edgeof the seat.,

`The length of the front and rear legs of the frontseatissuch,relatively,thattheseat-surface will be about horizontal and thelegs be slightly inclined toward the rear seat, D, when the front seatis in a proper position for use, as shown in Fig. 1.

The front and rear seats are connected by the parallel bars L,which havetheir rear ends, d, pivoted to the short front projecting limbs, C', ofthe rear limbs, C, that are attached to the rear seat, D, and theforward ends of these parallel bars L are attached by pivots to the endsof the short links M, which latter have their other ends pivoted to theinner sides of the ,rear legs, K, of the front seat.

Each rear leg, K, of the front seat is re-en` forced and thickened fromthe lower end to a point, e, upon the inner surface of each,where anoffset or projecting shoulder is formed, and as the ends of the links Marepivoted upon these re-enforced portions of the legs K, just below theshoulders e, it is apparent that the lower edges of the bars L will restupon the shoulders e when the front seat is elevated for use, as shownin Fig. l. The front ends of the parallel bars L being bent slightlydownward to allow their pivoted ends that connect the links M to liebelow the offset shoulders e, and the pivotal point of connection of therear ends, d, with the upwardly-inclined limbs C', lying in a planeabove the pivotpoints ofcounection of the forward ends of the parallelbars L with the links M, a lock of the front seat is assured. that isrendered immovable when the seat is occupied.

It will be evident upon an inspection of Fig. 2` that the rear seat, inadvancing from its rearward position,(shown in Fig. 1,)will be carriedupward and describeian are, as its limbs lie in a diagonal position,inclined toward the rear, when in the adjustment shown in Fig. l, andtheir length will be added to the height of the rocker-plateprojections, upon which they are pivoted, when the limbs F G are atright angles with the top edges of the rocker-plates A. Consequentlythere will be ample clearance-room between the top of the front seat andthe under side of the rear seat when theseats are being moved to assumethe position shown in Fig. 2.

If seat-supporting standards E are used in connection with the rear seatwhen thisseat is advanced to be used as a single seat and the front seatfolded, as shownin Fig. 2, the free lower ends of these standards E willrest upon the bent-over portions a of the front leg bracket-supports ofthe rear seat, to which the lower ends of these front legs, F, arepivoted, so that a stable base is thus afforded to the standards, whichsustain the weight placed uponthe seat in either a position of forwardor rearward adjustment. When the front seat is lowered forward, as shownin Fig. 3, and the rear seat advanced, the bent ends of the parallelbars L and the attached links M will together form arched braces, whichlock the front and rear seats in place, as adjusted, and when the seatsare located as shown in Fig. 4 they will be Similarly locked.

5 As is indicated in the statement of objects 1c forwardly or retracteda proper distance when the vehicle is used either as a double or singleseat conveyance.

The adjustable dash S is shown in Fig. 1 as forwardly extended. Theoperating mechanism ofthe extension-body and movable-dash consists of arail or front board, R, which is mounted on the front cross-sill, R',ofthe body-frame of the vehicle. f

The relative length of the foot-board R is 2o such that it will slidefreely within the sides of the vehiclebody, which latter may be cut awayin easy curves forward of the upright position of the front seat, so asto have the top edges of said sides inline with the top surface of thefoot-board R, as is usual in some forms of bodies, to afford room forthe free entrance of' seat occupants.

The breadth from the frontto the rear edge of the foot-board R is aboutequal to that of the transverse sillvpiece R', so that when thev dash isretracted to shorten its distance from the rear seat, when the latter islocated as shown in Fig. 2, the foot-board will belocated directly abovethe cross-sill R. The dash S` is mounted on the foot-board and securedthere-V to in the usual way.

It is essential for the proper operation of the movable dash S that itand its sustaining foot-board R should be slidingly but securely 4o heldin place on the cross-sill R, sothat it will not be liable todisplacement, either vertically or laterally. To effect this result in asimple and reliable manner, I provide two guiding parallel bars, U, oneof the bars being'shown in position in Fig. 10. Those bars U are both ofsimilartform and size, located near each side of the vehicle-body; hencea description of one will answer for both.A

The guide-bar U (shown'in Fig. 10) is made 5o of metal, preferably roundin cross-section, Vthe length of said bar being sufficient to permit itto be doubled, so as to afford two limbs, m a, the lower limb, a,beiuginserted through a hole made transversely in the cross-sill R,

of a size to allow the limb to slideneatly in it.

The upper piece or limb, m, of the bar U has an offset bend made in itat o to close the two portions m and n sufciently together from thispoint inwardly toward the integral loop 6a p to allow the upper limb, m,to slide above the upper surface of the cross-sill R. From the point 0toward the outer end, q, of the upper limb, m, this limb is parallel tothe lower limb, a, and at such a distance above that it may be insertedthrougha perforation made in the foot-board R, immediately above the.lower limb, a, of the guide-bar.

The length of the upper limb, m, is such,in regard to the breadth of thefoot-board R, that when it is forced through the hole made for it in thefoot-board until the shoulderois in contact with the inner edge of thefoot-board projecting ends are afforded to both the limbs m a, and onthese ends a vertical connectingbar, V, is secured to hold the limbsspread apart and parallel to each other, the upper limb being secured.rigidly to the crossbar R and the lower limb, a, free to slide in itsbox -or hole provided in the bedsill R'.

At the inner termination ofthe guide-bar U an integral eye, p, is formedtherein by the bending of the same, as has been explained, and aconnecting-bar, W, is pivoted to this looped end of the guide-bar by oneof its ends, the other end of the bar WV extending rearwardly asufficient distance when the seats are in the position shown in Fig. 1to he pivotally attached to a depending integral leg, to, which isformed on the rear limb, C, of the rear seat, D, and when the seats areboth in theposition therein shown the foot-board and dash wiil beextended forwardly to afford space for the proper occupancy of the frontseat.

lt will be observed that the dash-board wi ll be locked in eitherforward or rearward adjustment and the body of the vehiclecorrespondiugly extended or shortened bythe adjustment of the rear seatin a rearward or forward position, and as the bars W are located nearthe side sills of the body there will bc no obstruction of foot-spaceeffected by the operative mechanism of the foot-board and dash.

In Figs. 5 and 7 the foot-b0ard extension and movable dashboard areshown in connection' with another form of the j'umpseat mechanism, whichI have secured by patent already, and it will be seen that in thisapplication of the movable foot-board and dashboard the operatingbarsare also attached to depending legs formed on the front limbs of therear seat, so that the body will be lengthened or shortcned and the dashmoved outward 0r rearward by the act of changing of position of theseats of' the vehicle and be locked in any desired fpositionautomatically.

In case a movable footvboard is to be adj usted to afford foot-roomwhere there are jump-seats used in a vehicle-body that is of the pianoor rectangular form, as represented in Fig. 11, the dash is divided intotwo seetions, the upper portion, 1', being fixed to the front of thebody O by any suitable means and at any desired height to afford freefoot'space below it.

Upon the foot-board v, whichV is made similar to those shown in theother figures, a supplementary dash, r', is provided-that is, affixed tothe upper surface of the foot-board o-and this foot-board is adapted tobe shifted a proper distance forward to open a gap by the removal of thelower dash, r', or panel,

which is forwardly moved when both seats are in the upright position,(shown in Fig. 11,) or ready for use, the folding ofthe front seatvsliding the movable portion of the dash rearward a sufficient distanceto close up the opening and align it with the upper fixed part, r, ofthe same.

The gap on each side and top of the dash r', that is produced by itsforward proj ection,may be closed up by any suitable means that may bedesired, to afford a proper finish, as by winged panels affixed at theends of the dash. The lower portion of the dash may be paneled toconform in style to the vehicle-body and these wings, and thus present aneat uniform appearance when the lower dashboard is outy wardlyextended.

The top surface of the foot-board may be covered by an" apron of carpetor oiled cloth, X, to provide a suitable finish to the same, the coverbeing tacked or otherwise secured to the top surface of the foot-boardto move with it. Other means may be employed to finish up the insidesurface of the vehicle-body at its forward portion than those mentioned;hencel I do not restrict myself to the covering mentioned.

It is evident that, if preferred, the connectingbar WV may be pivoted tothe` side of the limbs G of the rear seat above .their pivoted points ofconnection with the v curved projections of the rocker-plates, and by achange of position nearer to or farther from these pivots the throw ofthe rod WV, and consequent movement of the foot-board R, may be altered.

It is not imperative that the connectingbars W be pivotcd to the frontlimbs of the rear seat, l), as by extending them rearwardly to a properlength they may be pivoted to the rear legs, C, of the rear seat belowtheir pivots on the rocker-plates. It is also evident that the slidingdash and its operating mechanism may be used in connection with otherjumpseat irons than have herein been shown and described; henceI do notwish to limit its usein this respect, reserving the right to combine themovable dash-board and its operating devices with any other style lof jump-seat irons available to act in connection therewith.

Another important feature of this invention is shown in Figs. 12 and 18of the drawings. It consists in the hinged attachment of the side arms,12, to the front seat of two j ump-seats. In the attachment of theseside arms the seat proper is first provided on its front and rear edgeswith plates 13,prcferably bent outwardly at each end to produce lugs orprojections 14, which are slightly beveled for a purpose pres entlyexplained. It is obvious that the plates 13 may not extend the entirewidth of the seat, but instead be made shorter, and one of these shortplates placed at each corner of the seat.

Pivoted or hinged to the plates 13, a short distance from the side edgesof the scat, are brackets or supports 15,*having their` upper portions,1G, bent inwardly at obtuse angles to the lower portions, as shown inFig. 13 in dotted lines. The portions 16 are also preferably bentforward slightly and have framed armrest-s 12 secured between them ateach side ofthe seat for the reception and support of cushions of anydesiredconstruction.` When the armrests l2are in their raised position,thelower portions of the brackets 15 will seat upon the beveled upperends of the lugs 14 and be snpported by said lugs, the cushions of thearmsupports and the cushion on the seat meeting and producing a neatjoint. By this construction when the armrests are lowered or folded downupon the seat they will move in the arc of a circle, and hence swingclear of the seatcushion at the side edges of the same.

The folding arms l2 may be given any preferred form or style toharmonize with that of `the rear seat, and thus provide a neat and ar-`latter is advanced to be used as a single seat.

Many slight changes might be madeuin the details of construction of thisinvention and not exceed the scope of the` same. I do not, therefore,restrict myself to the exact forms `Shown herein; but, v i
